Field Detail

aliases

Where we store a map from field name we expect to see in our query string, to Alias object containing the fields to use in our DisjunctionMaxQuery and the tiebreaker to use.

Constructor Detail

ExtendedSolrQueryParser

public ExtendedSolrQueryParser(QParser parser,
                               String defaultField)

Method Detail

setRemoveStopFilter

public void setRemoveStopFilter(boolean remove)

getBooleanQuery

protected org.apache.lucene.search.Query getBooleanQuery(List<org.apache.lucene.search.BooleanClause> clauses)
                                                  throws SyntaxError

Description copied from class: SolrQueryParserBase

Factory method for generating query, given a set of clauses. By default creates a boolean query composed of clauses passed in. Can be overridden by extending classes, to modify query being returned.

Overrides:

getBooleanQuery in class SolrQueryParserBase

Parameters:

clauses - List that contains BooleanClause instances to join.

Returns:

Resulting Query object.

Throws:

SyntaxError

addAlias

public void addAlias(String field,
                     float tiebreaker,
                     Map<String,Float> fieldBoosts)

Add an alias to this query parser.

Parameters:

field - the field name that should trigger alias mapping

fieldBoosts - the mapping from fieldname to boost value that should be used to build up the clauses of the DisjunctionMaxQuery.

tiebreaker - to the tiebreaker to be used in the DisjunctionMaxQuery
